How to add time to the current timestamp in Ansible?

Something like?

{{ ansible_date_time.date }}
{{ ansible_date_time.hour|int +1|int }}
{{ ansible_date_time.minute|int +15|int }}

If you are going to use lookup_plugins and pipe, you may just add 5 mins by using date +"%Y-%m-%d %r" -d "5 mins".

Thanks to

• Incrementing current date by 5 minutes

Nevertheless it is recommend to use Ansible variables like ansible_date_time from facts.

date_time:
  date: '2021-11-23'
  day: '23'
  epoch: '1637678908'
  hour: '15'
  iso8601: '2021-11-23T14:48:28Z'
  iso8601_basic: 20211123T154828773386
  iso8601_basic_short: 20211123T154828
  iso8601_micro: '2021-11-23T14:48:28.773386Z'
  minute: '48'
  month: '11'
  second: '28'
  time: '15:48:28'
  tz: CET
  tz_offset: '+0100'
  weekday: Tuesday
  weekday_number: '2'
  weeknumber: '47'
  year: '2021'

Form there you could use epoch, minute or what would fit to your use case.

You can use the strftime filter to format times, Ansible's built-in fact gathering to get the current time, and a little bit of arithmetic to add an offset.

  tasks:
    - debug:
        msg:
          - "{{ '%Y-%m-%d %r' | strftime(ansible_facts.date_time.epoch | int + 300 ) }}"
          - "{{ '%Y-%m-%d %r' | strftime(ansible_facts.date_time.epoch | int + 900 ) }}"
